Step 3: Replace the M40e and M160 Router Craft Interface

The craft interface is attached to the upper impeller assembly (front top blower).

Action

To remove the M40e and M160 router craft interface, follow these steps:

1. Attach an ESD wrist strap to your bare wrist, and connect the wrist strap to one of the two ESD points on the chassis.
2. Unscrew the captive screws at the corners of the impeller assembly (the craft interface).
3. Grasp the impeller assembly and pull it halfway out of the chassis. (See Figure 78.)
   

   CAUTION: If the impeller is still spinning, do not put your fingers or any tool into the impeller assembly as you pull it out. To avoid injury, wait until the impeller stops spinning before removing the assembly.

4. Pull the impeller assembly completely out of the chassis.
5. Place the assembly top-side down (the lettering on the craft interface is upside down) on an antistatic mat on a flat, stable surface.
6. Using a Phillips screwdriver, loosen and remove the four screws that secure the bottom of the craft interface housing to the impeller assembly.
7. Turn the impeller assembly over so that the lettering on the craft interface is right side up.
8. Using a Phillips screwdriver, loosen and remove the four screws that secure the top of the craft interface housing to the impeller assembly.
9. Using a Phillips screwdriver, loosen and remove the screws located on the rear side of the craft interface at the side. There are two screws at each side, located near the holes for the captive screws that secure the impeller assembly to the chassis.
10. Grasp the sides of the craft interface and pull it straight off the front of the impeller assembly.
